Paperboy
Research · Local stdio
Quality: 45/100 (Fair) | Auth: other
Verdict Summary: Choose Research Hub if you need specialized Research tools running via a local process. Choose Paperboy if your workspace requires Research integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Research Hub when:
You need dedicated capabilities in the Research domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (Free / Open Source).
You have access to required keys: ZOTERO_API_KEY, ZOTERO_USER_ID, NOTEBOOKLM_API_KEY, GOOGLE_API_KEY, GOOGLE_OAUTH_CLIENT_ID, GOOGLE_OAUTH_CLIENT_SECRET.
Primary tools included: Unified search across arXiv, Semantic Scholar, PubMed, and CrossRef, Integration with Zotero for reference management, Obsidian note syncing and dashboard visualization.
Research workspace MCP integrating Zotero, Obsidian, and NotebookLM. Search papers (arXiv/Semantic Scholar/PubMed/CrossRef), ingest into Zotero, sync notes to Obsidian, verify NotebookLM briefs. All three external tools optional. pip install research-hub-pipeline then research-hub serve.
Send research papers from Claude to a Kindle or Kobo, with Zotero as the source of truth. Searches arXiv and OpenAlex, recommends related work via the Semantic Scholar citation graph, queues papers in a Zotero collection, and delivers the PDFs by email or Dropbox. Receipts report file sizes and name anything that could not be sent.
